What's causing the Tesla fires?

With Tesla owners having reported 3 fires in 2 months, all the talk has been about the hazardous nature of driving around on a ton of electricity. However, I'm starting to think there might be more to these stories.

Tesla has been quick to point out that all 3 fires were a result of an accident. That's fair. Accidents happen and it's important to separate accidents from scaremongering talk of spontaneous combustion.

All three accidents involved the cars being driven over a hard object at speed, which in turn pierced the battery casing and started a fire. I'm curious to understand why Tesla owners are driving into things. Is it purely bad luck, or is it something more?

I have a theory.  It's completely speculative, but it is possible, nonetheless.  I wonder if these accidents may not have been entirely down to bad luck.  I wonder if they could have been worsened - perhaps even caused - by driver distraction. 

Could driver distraction be playing a role?

Never before has a driver been able to do so much behind the wheel of a car - over and above the primary task of driving! Never before have so many familiar, tactile controls been replaced with a cold smooth interface. Operating a Tesla Model S is unlike operating any other car.  And as brilliant as the technology is, it could be a lot more user-friendly.

Many of the car's functions - both simple and advanced - now require a visual check and a particular dexterity that was not needed in the chunky world of dials and buttons. In short, the interior of the Tesla Model S - as phenomenal as it may be - is potentially unsafe.

Lastly, we shouldn't underestimate the temptation presented by all that considerable computing power poised an arm's reach away. I'm tempted to use my iPhone all the time: when stopped at traffic, whilst waiting for a meeting, even during a meeting. It's not surprising that similar technology - super-sized and transplanted into a car - will sit there begging to be used, providing significant temptation, and inevitably distraction.

So are we perhaps missing something crucial with these fires? Rather than jumping to conclusions about the technology that propels these pioneering vehicles, perhaps we need to consider another possibility:

That indirectly, Teslas are catching fire because of a dangerous user experience.
